I know for example, Mandarin (Chinese) has it like from this sentence: 我睡了八個小時 (I slept for 8 hours), the hanzi: 覺 is omitted in this sentence because 睡 is already a word with its own meaning “sleep” 睡 which in itself conveys the meaning of the verb. There are “Euro” languages where separable verbs exist such as Dutch or German for example.
